This is due to the process of innovation under the U.S.big and venture business competition and the U.S.information policy.Two is the U.S.Information policy spurs the competitiveness of the U.S.InformationIndustry but until now, it cannot recovery the surplus in information electronics industry to the Asian Pacific countries and it caused to the U.S.enterprise structure.But my research dose not complete because of this industry's intensified changingin 1990s, and I cannot conclude.
